Description
TOOL FOR WORKING IN PIPES
REPAIRED UNDERGROUND
Field of the invention
The invention relates generally to devices used to work on repaired underground pipes.
Background of the Invention
Underground pipes can be repaired as follows: a fabric coated with a resin (or a similar type of liquid hardening) is inserted into a pipe at an exposed end, an inflatable device, similar to a balloon, is inserted into the fabric that runs along the length of the pipe, and, the inflatable device is inflated, allowing the liquid in the fabric to attach.
Repaired underground piping may include untimely obstructions of the fabric and / or dry liquid that is used to repair the piping. Any obstruction that could act to cause debris and other material to collect and, in turn, could cause blockage in the pipeline. However, since the pipe is located underground (or otherwise inaccessible), it can be difficult to remove the blockage safely without damaging the pipe and, specifically, the repaired part of the pipe.
While the devices may already exist, it is believed that there remains a need in the art for a device that
It can be inserted into the repaired underground pipe at an exposed point (such as an open end), but allows the user to work on the underground pipe at an unexposed point.
